You can do something like
system > every 1 sec
--- system > create object at position (random(0,layout.Width), layout/Height)
And use another event to make them fall. What kind of fall do you want to achieve? Do they should stop when they have reached a certain distance ?
Yes
I threw together a .capx file for you. Its kinda late here so I didn't have time to comment it much. I think you can figure it out though its pretty straight forward.
All it does is call for a random spawner object (one of 5) to spawn a random piece of 5 fruit every 3-4 seconds. The fruit and floor have physics so they fall and bounce but you can give the items bullet behaviors and set angle to 90 and whatever speed you like and do an on-collison or overlap with floor instead.
Hope it helps you see one way to put together multi-items selections without the complication of arrays.
thank you. I will download it and try it.
